use of α-cationic phosphonites derived from TADDOL as
ancillary ligands has allowed a highly regio- and enantioselective
synthesis of substituted [6]carbohelicenes by sequential Au-catalyzed
intramolecular hydroarylation of diynes. Key for these results is
the modular structure of these new ligands, and the enhanced reactivity
that they impart to Au(I)-centers after coordination.
